About

This repositories demonstrates the addition of new commands to the edward text editor. The editor provides a Scheme library interface through which new commands can be added. Using this library interface, the following commands have been implemented in this repository:

  1. A ctags command which set the current address to a given tag.
  2. An fzf command for changing the current file.
  3. A pipe command for filtering text using shell commands.
  4. A scroll command which is provided by many BSD ed(1) implementations.

Demonstration

Recording of a terminal session which demonstrates the usage of an enhanced version of the Unix text editor ed(1). The editor is used to display the contents of a Scheme source code file. Within this editor session, a "z" (scroll), "T" (ctags), and "F" (fzf) command is used to navigate the source code.

Installation

Assuming CHICKEN is already installed, run:

$ git clone https://github.com/nmeum/edward-contrib
$ cd edward-contrib
$ chicken-install

Afterwards, edward-contrib should be available in your $PATH.
